Hisham Tawfiq has an estimated net worth of $200,000. He plays Dembe Zuma on the show. Dembe is Redâs sidekick, security detail, and bodyguard. Dembe has always got Redâs back, scaring off any would-be assassins at every turn. Heâs been on the show since 2014 and frankly Red would probably be dead without him.
The speed of sound in a material, particularly in a gas or liquid, varies with temperature because a change in temperature affects the material's density. In air, for example, the speed of sound increases with an increase in temperature.At 32 Â°F. (0 Â°C.), the speed of sound in air is 1,087 feet per second (331 m/s); at 68 Â°F. (20 Â°C.), it is 1,127 feet per second (343 m/s).The terms subsonic and supersonic refer to the speed of an object, such as an airplane, in relation to the speed of sound in the surrounding air.he speed of sound depends on the elasticity and density of the medium through which it is traveling. In general, sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
passage through the air at speed greater than the local velocity of sound. The speed of sound (Mach 1) varies with atmospheric pressure and temperature: in air at a temperature of 15 Â°C (59 Â°F) and sea-level pressure, sound travels at about 1,225 km (760 miles) per hour. At speeds...
